ABSTRACT
From the fourth week of life, 1200 ISA Vedetta chicks were fed with one of four feed mixtures with
similar protein and energy contents, to which were added: 8.0% rape seeds (diet I), 4.0% lard (diet II) ,
5.5% by-product fat (diet III) or 3.5% sunflower oil (diet IV). The highest body weight achived
broilers fed diets with lard (P ≤ 0.01); feed utilization per kg gain was the best in this group too.
The cholesterol content of meat from broilers receiving the sunflower oil-containing diet was the
lowest, and the linolenic and linoleic acid contents in breast and thigh meat were the highest in
chickens fed the rape seeds-containing diet.
